Serves its intended purpose. Looks nice. Good price. The accuracy is just OK. It will definitely alert you to a severe voltage condition, however, the voltage indication reads high about one half volt around 14.5 V.

Ordered a 24 volt unit. Gauge looks fine but when I ordered it there was no indication that the 24 volt unit requires a special inline resistor. Found that out when I read the wiring instructions that came with the gauge. Now I have to reorder to get the resistor plus pay additional freight. It would be nice to know that when ordering or just include it with the gauge since it is required for proper operation.
